Download or read book Toxicity and Autophagy in Neurodegenerative Disorders written by José M. Fuentes and published by Springer. This book was released on 2015-05-04 with total page 277 pages. Available in PDF, EPUB and Kindle. Book excerpt: Comprehensive overview of different aspects of autophagy as it relates to neurodegenerative diseases. The pathogenesis of the main neurodegenerative disorders includes either the accumulation of altered or misfolded proteins or exposure to several toxics. Autophagy constitute one of the two principal cellular pathways implicate in the clearance of these material and can serve as a neuroprotective mechanism. Topics include: the role of autophagy in the brain, the role of autophagy in the principal neurodegenerative disorders, and the mechanism by which different molecules cause neurotoxicity and the role autophagy plays.
Download or read book Autophagy written by Tomohiro Kabuta and published by Elsevier Inc. Chapters. This book was released on 2013-07-29 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: To date, three forms of autophagy – macroautophagy, microautophagy, and chaperone-mediated autophagy (CMA) – have been identified. Recently, we discovered a novel type of autophagy, “RNautophagy,” in which RNA is taken up directly into lysosomes for degradation. Gain of toxic functions of accumulated misfolded proteins or abnormal RNAs in CNS participate to a considerable degree in the pathogenesis of various neurodegenerative diseases. Thus, degradation and clearance of the toxic species by autophagy systems may be important for the maintenance of neurons and prevention of neurodegenerative diseases. We showed that amyotrophic lateral sclerosis (ALS)-linked mutant SOD1 is degraded not only by the proteasome but also by macroautophagy, and that macroautophagy reduces mutant SOD1-mediated toxicity. We found that Parkinson’s disease-associated mutant UCH-L1 interacts with LAMP-2A and Hsc70, which are the components of CMA machinery, and inhibits CMA. Because RNAs containing aberrant repeats are thought to cause some of ALS or spinocerebellar ataxia (SCA), RNautophagy may also play significant roles in the pathology of neurodegenerative diseases.
Download or read book Autophagy of the Nervous System written by Zhenyu Yue and published by World Scientific. This book was released on 2012 with total page 441 pages. Available in PDF, EPUB and Kindle. Book excerpt: What is autophagy? Why would neurons digest parts of themselves through autophagy? How can autophagy save the lives of cells under some conditions, but act as an accomplice to cell death in others? By what mechanisms are autophagy-related processes dysregulated in neurological diseases, and are there therapeutic strategies to correct or compensate for their dysfunction? This book provides an expert view of major concepts in autophagy research with a focus on autophagy in neurons. Experimental evidence for evolutionarily conserved and specialized regulatory mechanisms for autophagy in the mammalian nervous system will be presented, including recent data on braking mechanisms. Areas of intersection with cell death, the ubiquitin-proteasome system, chaperone-mediated autophagy, and the endocytic pathway will be reviewed, along with emerging areas of mitochondrial autophagy (mitophagy) and the autophagic regulation of neuritic/synaptic processes. Advances in delineating mechanisms by which autophagy is involved in the pathophysiology of neurological disorders, including Alzheimer's, Parkinson's, Huntington's, amyotrophic lateral sclerosis, ischemia/hypoxia and lysosomal storage diseases, will be discussed along with current drug development strategies targeting autophagy.

Download or read book Autophagy written by S. Tariq Ahmad and published by Elsevier Inc. Chapters. This book was released on 2013-07-29 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: Autophagy is a highly regulated process that promotes vital cellular homeostasis by allowing bulk non-specific degradation of the cytoplasmic contents, mainly damaged and/or surplus organelles and proteins. Autophagy is ubiquitous in eukaryotes, highly conserved from yeast to mammals, and occurs in all mammalian tissues. Historically, autophagy was characterized as the coping response to limited energy resources (starvation), to generate additional biomolecular raw materials. However, research in the past two decades has demonstrated the indispensible roles of autophagy in eukaryotic physiology and pathology with respect to wide-ranging processes such as development, differentiation, aging, immunity, cancer biology, and neurodegenerative disorders. In this chapter, we will provide an overview of the types of autophagy and mechanisms of the autophagy pathway followed by a discussion of the current understanding of the role of autophagy in neuronal physiology, pathology of neurodegenerative disorders, and potential therapeutic approaches.

Download or read book Polyglutamine Disorders written by Clévio Nóbrega and published by Springer. This book was released on 2018-02-09 with total page 469 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a cutting-edge review of polyglutamine disorders. It primarily focuses on two main aspects: (1) the mechanisms underlying the pathologies’ development and progression, and (2) the therapeutic strategies that are currently being explored to stop or delay disease progression. Polyglutamine (polyQ) disorders are a group of inherited neurodegenerative diseases with a fatal outcome that are caused by an abnormal expansion of a coding trinucleotide repeat (CAG), which is then translated in an abnormal protein with an elongated glutamine tract (Q). To date, nine polyQ disorders have been identified and described: dentatorubral-pallidoluysian atrophy (DRPLA); Huntington’s disease (HD); spinal–bulbar muscular atrophy (SBMA); and six spinocerebellar ataxias (SCA 1, 2, 3, 6, 7, and 17). The genetic basis of polyQ disorders is well established and described, and despite important advances that have opened up the possibility of generating genetic models of the disease, the mechanisms that cause neuronal degeneration are still largely unknown and there is currently no treatment available for these disorders. Further, it is believed that the different polyQ may share some mechanisms and pathways contributing to neurodegeneration and disease progression.

Download or read book Mitochondrial Inhibitors and Neurodegenerative Disorders written by Paul R. Sanberg and published by Springer Science & Business Media. This book was released on 1999-10-01 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mitochondria have long been the Rodney Dangerfield of cellular organelles. Believed to be the remnants of bacterial infection of eukaryotic cells eons ago, the mitochondrion evolved a symbiotic relationship in which it dutifully served as the efficient source of A TP for cell function. The extraordinary dependence of cells on the energy provided by mito chondrial oxidative metabolism of glucose, especially through critical organs such as the heart and brain, is underlined by the fatal consequences of toxins that interfere with the mitochondrial electron transport system. Consistent with their ancestry, the mitochondria have their own DNA that encodes many but not all of their proteins. The mitochon dria and their genes come from the mother via the ovum since sperm do not possess mitochondria. This extranuclear form of inheritance derived exclusively from the female side has proven to be a powerful tool for tracing the evolution by the number of base substitutions in mtDNA. That mitochondrial gene mutations might be a source of human dis ease became evident a decade ago with the characterization of a group of multisystem disorders, typically involving the nervous system, which are transmitted from mother to child. Specific point mutations in mtDNA have been associated with the different syndromes.

Download or read book Protein Quality Control in Neurodegenerative Diseases written by Richard I. Morimoto and published by Springer Science & Business Media. This book was released on 2012-12-13 with total page 145 pages. Available in PDF, EPUB and Kindle. Book excerpt: The health of the proteome depends upon protein quality control to regulate the proper synthesis, folding, translocation, and clearance of proteins. The cell is challenged constantly by environmental and physiological stress, aging, and the chronic expressions of disease associated misfolded proteins. Substantial evidence supports the hypothesis that the expression of damaged proteins initiates a cascade of molecular events that leads to Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, Huntington's disease, and other diseases of protein conformation.
Download or read book Neurodegenerative Diseases written by Annette Simon and published by . This book was released on 2017 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neurodegenerative diseases are widespread disorders, with prevalence increasing with age. The first chapter of this book discusses autophagy, a cellular tool for the elimination of proteins that accumulate in neurodegenerative disorders and have pathogenetic significance. Parkinson's disease (PD) is one of the most common degenerative diseases of the central nervous system. Chapter Two examines evidence on impairment of social cognition in patients with PD. Chapter Three discusses how finding the molecular cause of the PD could contribute to early diagnosis, and facilitate the development of effective neuroprotective or modulatory drugs. The final chapter reviews the functional role of adult hippocampal neurogenesis in learning and memory, and how this form of structural plasticity is altered in neurodegenerative diseases known to involve cognitive impairment such as Alzheimer's disease, Parkinson's disease, and Huntington's disease.
